Thanks, that's helpful for me. By chance do you know if the class is natively recoverable from the TypeName for Clojure/Java? Class/forName can't roundtrip that string. I could implement a look-up table to translate between the two formats, but that seems rather kludgey. I actually just wrote a library for this sort of thing that works with any java.io.Serializable: https://bitbucket.org/morgon/jfreeze It's only meant to work with pr-dup (set the *print-dup* dynamic to true before printing), not necessarily the standard REPL printer, but generally if you're printing something you want to read back in you should be using pr-dup anyway. -- Morgon -- You received this message because you are subscribed to the Google Groups Clojure group.

Thanks, that's helpful for me. By chance do you know if the class is natively recoverable from the TypeName for Clojure/Java? Class/forName can't roundtrip that string. I’m not sure what you mean? The type of the array displays as [Ljava.lang.String; and when you do Class/forName on [Ljava.lang.String; you get back a Class that represents an array of String. The TypeName is just a human-readable form, not an actual Class name.

This is an interaction with Clojure via CIDER. repl [1] (type (into-array String [Awesome])) [Ljava.lang.String; repl [2] [Ljava.lang.String; RuntimeException EOF while reading, starting at line 1 clojure.lang.Util.runtimeException (Util.java:221) repl [3] (quote [Ljava.lang.String;) CIDER won't let me enter [3] claiming that the input is not complete. What's going on here, apart from things not working? If [Ljava.lang.String; is a valid return value, and can show up in code that I construct programmatically, why is it not valid input? Is this a flaw in CIDER / lein, or are they giving me the right answers here? -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: breaking homoiconicity?
Most Java types don't have reversible serialisation in Clojure. There's actually only a small subset of data types that can be printed and then read without losing information. - James On 20 June 2015 at 01:08, Joe Corneli holtzerman...@gmail.com wrote: This is an interaction with Clojure via CIDER. repl [1] (type (into-array String [Awesome])) [Ljava.lang.String; repl [2] [Ljava.lang.String; RuntimeException EOF while reading, starting at line 1 clojure.lang.Util.runtimeException (Util.java:221) repl [3] (quote [Ljava.lang.String;) CIDER won't let me enter [3] claiming that the input is not complete.
